Title: Drive circuit for pulse motor
Inventor: KAZAOKA HARUO
IPC: H02P8/32
Filed: 1980-09-02
Abstract: PURPOSE:To suppress vibration over a wide pulse rate range, by providing a damper. CONSTITUTION:In responce to the pulse motor driving signal sent from the outside, pulse signals phi1-phi4 different in phase from each other are applied to the respective bases of transistors Q1-Q4. When phi1 is applied to Q1, a current flows through a winding 8 via R1. Q1 turns off after a short time, however Q3 fed with phi3 at this time has not turned on. Therefore, a transient current flows through a closed loop consisting of the winding 8   a capacitor C3   a winding 10, generating Joule heat in the windings, so that a pulse motor is damped. Said capacitor C3 has an electrostatic capacity selected so as to be effective in case of a relatively high pulse rate. In case of applying a signal of low pulse rate, a switching circuit 20 is turned on to connect C5 in parallel in order to increase the capacity so that a sufficient damping effect is obtained.

Filed: 1980-09-03
Abstract: PURPOSE: To enable to enlarge sufficiently waterway in parallel with Venturi tube and to have a miniaturized and highly efficient pump by enabling to set a flange part through arrangement of flat part on the jet pump body.  
     CONSTITUTION: A plate-like flange 10 is set on a setting mouth 7 spirally joined with inlet of the nozzle waterway 1 and the body 6 of Venturi tube 3 through flat packings 8, 9 and a waterway is formed by a radial notch 17 on the screw part spirally joined with Venturi tube 3, wherein the notch 17 can be enlarged radially up to the screw part to fix flangege 10, resulting in obtaining a sufficiently large sectional area of waterway.

Title: Slip control device in direct coupling clutch for fluid coupling
Inventor: USHIJIMA FUMIHIRO
IPC: F16H61/14
Filed: 1986-05-27
Abstract: PURPOSE:To eliminate the necessity of electrical control to aim at enhancing the reliability and the like, by providing a pump driven by the difference in rotational speed between a drive side member and a driven side member, for generating fluid pressure, and a device for transmitting the fluid pressure delivered from the pump, proportionally to a direct coupling clutch. CONSTITUTION:When the amount of slip in a direct coupling clutch increases. the difference in rotational speed between a front cover 10 and an output shaft 26 increases, and therefore, the discharge pressure effected in the discharge port 70 of an internal gear pump 62 is increased. Further, this hydraulic pressure is fed from a port 90 into an oil chamber 84 in a drain valve 72 so that a spool valve 76 is moved leftward overcoming a compression coil spring 80. Accordingly, the degree of communication of a port 86 with a train port 88 is decreased so that the drop of hydraulic pressure in a torque converter chamber 14 is decreased while hydraulic pressure acting upon a piston element 34 is increased. As a result, the pressing force of a clutch surface section 36 against a clutch lining 38 is increased, thereby the transmission torque capacity of the direct clutch is increased.

Filed: 1990-05-11
Abstract: PURPOSE:To prevent generation of hydrogen at a negative electrode by using an electrolyte formed by the dissolution into a polar solvent of a pair of redoxes combined to each other in a specified way. CONSTITUTION:A redox secondary battery comprises a solution of divalent or trivalent vanadium formed by dissolution of an active material on the negative electrode side of a pair of redoxes into a polar solvent and a solution of halogen or halogen ions or that of divalent or trivalent iron formed by dissolution of an active material on the positive electrode side of the pair of redoxes into a polar solvent. The pair of redoxes are supplied to a liquid transmission type electrolyte bath so that the battery is charged or discharged. Because the potential of the electrode reaction of divalent or trivalent vanadium redox ions is positive as compared to chrome ions and the electrode reaction takes place at high speed, the negative electrode reaction is not accompanied by such an auxiliary reaction as generation of hydrogen, etc., and the Coulomb efficiency of the charge and discharge of the battery is high. In addition, the electrode reaction of halogen or iron at the positive electrode takes place so rapidly that the battery can be easily designed and manufactured.
